I'm getting the same crash. Sometimes the game crashes before I can even get to the multiplayer server view.

Here is info from the Windows Event Viewer. Not sure if it helps.

I tested this with all the vehicles. And both the gunner optics azimuth and the radar compass (displays 000) on all vehicles stopped working with the latest patch.

The problem with Arma 3 is that gun recoil moves your focus of attention. In reality recoil moves the gun, but does not move the point where the shooters attention is focused.

And this is especially frustrating cause there obviously is a mechanism in the game that allows the moving of the gun without moving the point of focus.

When you stand up and bring up your sights, the weapon will have a degree of sway. But no matter how long you stand there the point of focus will not move. And the weapon sights will just sway around the stationary point of focus.

Having to compensate the recoil with the mouse is dumb game mechanic that makes it harder to lead moving targets with auto weapons compared to semiautomatic weapons. Which is the complete opposite of how it's supposed to be. It also limitis the burst lengt to the length of your mouse mat.
And you can't even build up a muscle memory for compensating for the recoil, cause the angular sensitivity changes based on what sight you are using, whereas the recoil stays the same. So if you practice compensating the recoil using your iron sights, you're completely screwed when switching to, lets say, the MG optics.

I have my compass in 'R', and I have my inventory at 'OEM102 + R'. And whenever I open my inventory the compass flashes on the screen. Previously I had my inventory at 'L.Shift + R' and the same happened then. The same glitch is in Arma2OA too.

However I think this is a very low priority, considering what other issues are out there.

This happens every time I start the game. I play most games with speakers, but with arma one really needs to use headphones to be combat effective. So I start the game with speakers as the default sound device. Notice immediately that I have the wrong sound device. But still have to wait 30 seconds for the game to start and get me to the menu, so I can exit and start the game again.

Not exactly game breaking, but annoying none the less.
